Established in 1998, NEMA’s LSI is a composite measure of lamps, luminaires, ballasts, emergency lighting, exit signs, and other lighting products shipped nationally and internationally from the United States by the 450 companies that comprise the National Electrical Manufacturers Association (NEMA). Adjusted for the season and inflation, the Index uses 2002 data for its 100-point benchmark. View it at www.nlb.org/Index.

“The first quarter of 2010 was the third consecutive quarter of LSI growth, and it gave us reason to believe a sooner-rather-than-later turn-around was possible. That optimism was dashed when 2010’s second-quarter performance showed a 0.3% decline,” Bachner said. “Right now it appears that the situation is holding steady; that any future declines are likely to be slight; and that improvements also will be sight, but they’re still likely to outnumber declines.”
